Electric fuel pump oppinions
Hi All, I'm thinking of putting a Holley 12-802-1 electric fuel pump and regulator on my 69 427 3x2. My car is a driver. I am not overly concerned with correctness (I do keep all original parts).
My car is running lean and loses power dramatically at 4000 rpm ish and will on occasion burp. It is a stock L68 set up. I have checked everything from tank to carbs. Fuel pressure at best is 4.5 upstream of the 3 way 90 degree splits that feed the carbs. As revs increase (no load condition) the fuel pressure decreases so I am sure I need an new pump.
Outside of "correctness", has anyone had experience or knowledge of the holley elec pump on our cars positive or negative?
All comments much appreciated.
Later, Rog.

I had one on my 76 that I sold. I had problems with it dying on turns and WOT. I had to eventually install a fuel sump in the gas thank to make sure there was always fuel to the line. After that it ran great. Don't scimp on the regulator either.
Good luck.
Good luck.

Not trying to deter you from an electric pump but why not just install a good fuel pump. There are plenty of tri powers running around with a lot of HP running a stock style mechanical pump that feeds the carbs fine. I ran my 500 HP SB on a dyno with a Holley mechanical fuel pump and it maintained 6 psi from idle to 6500 rpm without a problem.

My 427 build is running almost 600hp and I am using a Holley Mechanical pump with regulator.
Plenty of fuel psi
If you want to step up to a very nice mechanical pump take a look at the ones made by RacePumps.com I used one on my 540 and they are good to 2500hp!

As far as the electric pump, I have had good luck with them ONLY when you run a bypass type regulator, if you try a deadhead regulator you WILL kill the electric fuel pump if not right away but down the road

Also am scared of product quality. If I get a type 40482 ac Delco Pump is it the same as the one that came from the factory or is it a rebuild or inferior for some reason? I would like to put on an original pump but with a holley I am sure to be able to get the fuel I need.
Should I be confident with a NOS pump? I really don't know? any thoughts?

Here is the part number of the holley pump I purchased from Summit
HLY-12-454-20 pump
HLY-12-803 regulator
Note that you will need fittings for that pump that have o-rings
I am running 8an Earls type fittings on mine
All said and done you might be better with a stock gm pump
If not I know for sure you will have more than enough fuel psi with this pump or the one from racepump.com

Aeromotive Street and Strip electric fuel pump with an Aeromotive speed controller. The speed controller applies a lower voltage to the fuel pump (actually chopped 12 volt DC) at idle and then slowly increases voltage to the pump up to 2500 rpm (?) when it applies full DC to the pump. This reduces pump speed at low engine rpms and thereby reduces the noise of the pump. Also, the speed controller turns off the pump when you turn off the ignition so you don't need a oil pressure turn off switch.
The Aeromotive pump and a filter are located back near the fuel tank outlet and the regulator (the traditional Holley regulator that's been sold for 30 years) is located up near the carb.

Fonz69--Yes Sir: I'm running an electric fuel pump, approx. 6.6 # of Pressure with no by pass line. With a 350 small block, I have gone through 2 pumps already, one for each year it's been running. Are you saying this is creating the pumps to go out. No fuel pressure regulator in system. Thanks for all the info. Gene

When I tried an electric Holly pump, I hated the hum of the pump so I switch to an Edelbrock mechanical pump.
I have 3 cars all running Edelbrock mechanical pumps. My bracket racer uses a regulator for consistency but it's not required. Can't beat the reliability of a mechanical pump.
